TIME Magazine cover subject Marco Rubio delivered the GOP’s response to President Obama’s State of the Union address last night. But while it was a big moment for the 41-year-old Florida Senator, and a chance for the Republican Party to counter Obama’s wide-ranging speech, the most memorable moment of Rubio’s night was when he nervously leaned over to grab a bottle of water and take a big gulp.

Several parody accounts sprang up almost instantly — for Rubio’s water bottle and for its maker, Poland Spring. The Senator was happy to join in the joke, posting a picture of his near-empty bottle of water after the speech on his Twitter account.

This isn’t the first time the thirsty Senator has had water issues during a speech. Taking the stage after that memorable Clint Eastwood performance at the Republican National Convention last August, Rubio — having taken a sip from a bottle on the podium — joked, “I think I just drank Clint Eastwood’s water.”
